Unless noted otherwise, the allowable uniform transverse loads are for panels installed under simply supported, single span conditions. Where loading conditions result in the panels resisting combined stresses, the sum of the ratios of applied loads over allowable loads must be less than 1.0. When used as shear walls under the IBC or IRC, the panels are limited to use in Seismic Design Categories A, B, and C. The bottom channel and wall cap and connections must be designed to resist the applied forces. 4.2 Installation: General: Installation of Snap-N-Lock Composite Panels must comply with this report and the manufacturer's published installation instructions. The manufacturer's published installation instructions must be available at the jobsite at all times during installation. The panels used as wall panels are installed with base channels and wall caps. Hat channels, jobsite-attached to the panel facings, are used to attach the interior finish to the wall and roof panels. The panels are connected to each other along their edges using the Structall SNAP-N-LOCK TM fastening system. Wall and roof panels must be installed with a continuous bearing support at each end of the panel span, with the supports providing a minimum bearing width of 1 inch (25.4 mm). As an alternative to restraining the roof panels subjected to uplift wind loads, the panels must be fastened with minimum No. 10 sheet metal screws with a 1.5-inch-diameter (38 mm) plate washer spaced no more than inches (305 mm) on center. The fastener must be at least 1 inch (25.4 mm) longer than the laminated roof panel thickness. Unless noted otherwise in this report, the steel facings of the wall panels must be attached to the top and bottom channels as shown in Figures 1 and 2. When used as racking shear walls, the panels require additional fasteners along the base and top tracks, as well as the vertical seams. See the fastening schedule in Figure 5. Wall openings must be framed with conventional materials and must be designed to the satisfaction of the code official. When used as bearing walls, the wall panels must be installed in the manner described in the footnotes to Table Thermal Barrier: Wall and Roof: One-half-inch-thick (.7 mm) regular gypsum wallboard, complying with ASTM C36 or ASTM C1396, must be installed on the interior surface of wall and roof panels. The hat sections are spaced inches (610 mm) on center and are fastened to the panel facings with No. 10 by 3 / 4-inch-long (19.1 mm) self-tapping screws spaced at inches (305 mm) on center. The gypsum wallboard is fastened to steel hat section channels described in Section 3.2.5, with minimum 1.0-inch-long (25.4 mm), No. 6, Type S drywall screws spaced in accordance with ASTM C840 for use under the IBC, or Table R of the IRC, using -inch-on-center (406 mm) framing spacing guidelines Panel Cladding: Roof Covering: A roof covering complying with Chapter 15 of the IBC, or Section R901 of the IRC, as applicable, must be installed on the exterior side of the roof panels. Roofs with hot-asphalt or hot-coal tar pitch are prohibited. Underlayment and flashing must be installed in accordance with the applicable code. The roof covering must be installed to resist the applicable forces, to the satisfaction of the code official. The roof covering must be installed in accordance with Structall s recommendations. Where required by the code official, the attachment of the roofing material to the roof panel must be designed by a registered design professional Exterior Wall Covering: For the installation of wall panels without a water-resistive barrier, a 1 / 4-inch (6.4 mm) bead of sealant must be applied to the panel joints prior to the panel s being engaged. Panels must be firmly interlocked to make continuous contact with the sealant. Erection proceeds along the wall elevation, with installation of successive panels in accordance with Structall s published installation instructions. Provided the sealants and application of the sealants are satisfactory to the code official, panels exposed to weather do not require a water-resistive barrier complying with Section 05 of the IBC when panels are installed with sealant as specified in this section (Section ) and are flashed. Flashing must be placed in accordance with Section 05.4 of the IBC on both ends of the panels when installation is at the building s base, and at eaves, openings, and horizontal and vertical corners. The flashing and trim are attached to the panels using 1 / 4- self-tapping screws or No. 10 by 3 / 4-inch (19 mm) self-tapping or self-drilling screws, or pop rivets in accordance with Structall s installation instructions. For the installation of wall panels with a water-resistive barrier, the exterior face of the wall panels is required to be covered with a wall covering complying with the applicable code or recognized in a current ICC-ES evaluation report. Flashing in accordance with Section 05.4 of the IBC or 2015 IRC Section R703.4 (20 IRC Section R703.8), as applicable, must be installed.
